there has been some speculation about Apple's "Retina" display for
the iPad 2, there have been few details regarding the tablet's resolution --
MacRumors suggests that
simply doubling the iPad's current resolution (1024x768) to 2048x1536 at a 260
DPI would result in a display that, while not exactly "Retina", would
be easier for developers to adapt to. Apple doubled its resolution on the
iPhone when it introduced the iPhone 4 for this very reason, with older apps
This approach is looking more likely, considering version 1.1 of Apple's iBooks
app accidentally included artwork for a pixel-doubled iPad. The bookmark icon
included art for the iPad, iPhone, iPhonex2, and iPadx2. The x2 versions are
exactly double the resolution of the original versions. The graphics have been
removed in subsequent versions of the app.
While this isn't, by any means, confirmation that the iPad 2 will be double the
resolution of its predecessor, it certainly is evidence that it may be
But a doubling of resolution also requires some additional graphics processing
power. AppleInsider reports that
this will come in the form of the a new custom A4 chip, jumping from from
the SGX535 to the new SGX543 graphics and video core, reportedly doubling the
processing power at the same clock speed. The new core also supports
The new A4 also includes acceleration for video encoding and decoding, meaning
improved video-conferencing via the FaceTime app. It could also mean HDMI
support -- already on Apple TV -- for the iPad and iPhone.
An AI source, described as "familiar with Apple's
graphics strategy," said the company would most likely be going to
multiple cores, as well. According to the source, "The most likely
configuration of Apple's next custom chip is reportedly the SGX543MP2, which
pairs two SGX543 cores to work as one, offering around four times the
capability of the previous A4 in graphics and video tasks."
As for general purpose processing, Apple will likely employ multi-core ARM Cortex-A9.
